Technical Field

The invention relates to the field of automobile half-shaft machining instruments, in particular to an automobile half-shaft heating structure.

Background

The forming of the flange plate is very important in the blank forging process of the automobile half shaft, and the end part of the blank needs to be heated so that the blank has better plasticity. Heating of the ingot is generally carried out by means of induction heating coils, such as the induction heating device disclosed in application No. CN201820947046.8, but the following drawbacks are often present: 1: a cooling water for cooling heating coil is for singly advancing singly to go out the form that heating coil one end is intake one end and is gone out water, and heating coil's cooling effect can not satisfy far away, fragile, and it is comparatively frequent to change, and the industrial production level is low, 2: when the heating is carried out by manual material clamping and feeding, the heating coil is easy to be damaged due to blank collision and the like, and the industrial production level is further reduced.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the automobile half-shaft heating structure, and the cooling efficiency of the heating coil pipe is improved, the replacement frequency of the heating coil pipe is reduced, and the manufacturing industrialization level of the automobile half-shaft is improved by a two-inlet and two-outlet cooling water introducing mode.

An automobile half-shaft heating structure comprises a heating coil pipe, a water inlet pipe and a water outlet pipe, wherein the water inlet pipe and the water outlet pipe are arranged on the heating coil pipe; the heating coil pipe comprises a first coil pipe section and a second coil pipeline which are mutually connected at the end parts, and a water inlet pipe and a water outlet pipe are arranged on the first coil pipe section and the second coil pipeline. In the technical scheme, the cooling water inlet mode is changed, two groups of water inlet pipes and water outlet pipes are arranged, the two-inlet two-outlet cooling water inlet mode is formed, the cooling efficiency of the heating coil is improved, the replacement frequency of the heating coil is reduced, and the manufacturing industrialization level of the automobile half shaft is improved.
